  2. An RBAC role assignee can unexpectedly change a DAG that is outside the management role group scope in an Exchange Server 2010 environment

An RBAC role assignee can unexpectedly change a DAG that is outside the management role group scope in an Exchange Server 2010 environment

Symptoms

Consider the following scenario:
  • You have some database availability groups (DAGs) in a Microsoft Exchange Server 2010 environment.
  • You create a management role assignment in the environment.
  • You assign management roles to a role assignee.
  • You define the scope of the role assignment to a member mailbox server in a DAG.
  • The role assignee tries to make some changes to another DAG that is outside the scope of the management role group by using one of the following cmdlets:
    • New-DatabaseAvailabilityGroup
    • Set-DatabaseAvailabilityGroup
    • Remove-DatabaseAvailabilityGroup
    • Stop-DatabaseAvailabilityGroup
    • Start-DatabaseAvailabilityGroup
In this scenario, the role assignee can unexpectedly change the DAG successfully.
